And they're available inexpensively or even free.īuying used gear is most often technically just as illegal as grabbing the images from some file sharing site because the licenses are not transferable. There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional. The phones gain access via a user-configured voice VLAN and can perform critical voice function, such as calling help desk, etc.If your goal is to run GNS3, then you need to get the IOS images in an appropriate way.īut, if you're trying to work with a lab setup, consider getting the actual physical gear. Critical VLAN support for voice devices allows a fallback mechanism when the authentication server is unreachable, for example, when the WAN link is down. If the authentication server becomes unreachable, IP phones cannot authenticate and therefore do not have connectivity.
Critical VLAN support for voice devices: Under normal circumstances, when an IP phone successfully authenticates on a port, the authentication server puts the phone into the voice domain. ASP can now leverage Device Classifier (DC) for device classification and execute the configuration macro associated with it for these new device types. AutoSmartPorts (ASP) automates the process of interface configuration by applying pre-defined configuration on an interface when a device is connected to the interface, and removing the configuration when the device is disconnected. The enhanced Device Classifier provides increased device visibility for the following new devices: Apple devices, 3 rd party phones and APs, 3 rd party printers, Cisco phones and conference systems, Cisco wireless LAN controllers, Cisco IP cameras, Cisco APs, Cisco digital media players, gaming consoles, smart phones among others.
